Hadrons as holograms — •Hilmar Forkel — ITA, Sao Paulo, Brazil — Institut fuer Theoretische Physik, Uni Heidelberg

Since the inception of QCD, progress in understanding its low energy realm was hampered by the scarcity of adequate techniques for handling strongly coupled Yang-Mills theories analytically. The discovery of the AdS/CFT correspondence and its gauge/gravity generalizations have given promise for this situation to improve in a qualitative way. Indeed, the ensuing dualities explicitly relate gauge theories at strong coupling to physically equivalent string theories in ten-dimensional spacetimes which become tractable at least in the weak (string) coupling and curvature limits. These dualities are manifestations of the holographic principle and have triggered an entirely new way of thinking about nonperturbative QCD.

We will outline the basic physical principles which underly the gauge/gravity correspondence and discuss approximate holographic QCD duals which were recently employed to describe the Regge behavior of excited mesons and baryons as well as glueball properties.
